Common steel delivery status
1) Cold rolling
u The advantages of cold rolling are good dimensional accuracy ,surface quality ,low surface roughness ,high mechanical properties.
u The steel surface of the cold-rolled (forging) state delivery has oxide skin coverage and there is a great internal stress, so likely to suffer corrosion or rust,.Therefore , its packaging and storage have relatively strict standards
2) Hot rolling
u Hot rolling (forging) steel plate’s termination of a temperature is 800-900 degrees Celsius, then generally natural air cooling.
u Hot-rolled steel state because of the surface is covered with a layer of oxide scale,so having some corrosion resistance, less stringent storage and transport requirements, unlike steel cold-rolled state delivery.
| Surface finish | Characteristics and application |
| No.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties,No2B could nearly satisfy comprehensive uses. |
| No.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
| 8K | The product have excellent brightness and prefer reflexivity can to be the mirror. |
| NO.1 | Hot rolled, annealing, pickling. Usually used to cold rolled material, pot for industry, device for the chemical industry and so on. |
